Hi,

I'd like to write a script to generate HCL colormap, and then transform it to RGB. Can anyone help with the transformation?

Thank you, Guy

Can you please clarify that you are actually talking about this HCL colour space and not HSL or HSV or some other colour space.

As far as I know, HCL is not used much. It's not a colour space directly supported by matlab although nothing stops you from writing your own conversion formula.

Hi all,

Sorry, already answered myself. I am using this great function, and specific for me (CIELCH->RGB)

@Abishek, all your answers appear to be (non-working) links to the doc with no comment whatsoever. That's fairly low quality in my opinion, and you could at least make them hyperlink.

Additionally in this case, your answer is not remotely helpful because the HCL colour space is not the same at all as the HSV colour space.
